Beyond species diversity: Functional responses of cave arthropods to microclimatic stability and structural complexity

open access: yesEcological Entomology, EarlyView.
Species richness declined along cave microclimatic gradient, while diversity increased with habitat heterogeneity, highlighting distinct roles of abiotic conditions and structural complexity in shaping arthropod communities. Functional traits shifted along the microclimatic gradient, with larger‐bodied and more eye‐regressed arthropods dominating under

Human Disturbance but Not Predation Risk Is Associated With Increased Vigilance in Roe Deer

open access: yesEthology, EarlyView.
Roe deer vigilance is lower in natural than in modified habitats, decreases with group size, but is not significantly influenced by stable wolf presence, suggesting habitat‐driven risk perception and reliance on spatial avoidance over increased alertness.

Identifying Purse Seine Vessel Operations Through Machine Learning Models for Better Spatial Fishing Effort Estimates

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Spatial fisheries management requires precise, spatial explicit information on species distribution and fishing impacts. In the NW Mediterranean, the distribution of small pelagic fish (SPF) stocks is currently assessed through annual acoustic surveys.

Experimental Investigation on the Impact of Sand Particle Size on the Jet Pump Wall Surface Erosion

open access: yesJournal of Marine Science and Engineering
Silt removal is crucial for maintaining navigable waterways in harbors. Jet pumps, without moving parts, are highly suitable for underwater operations such as channel dredging in port environments.

Growth and Condition of Largemouth Bass (Micropterus nigricans) and Bluegill (Lepomis macrochirus) in a Minnesota, USA, Lake with Separate Dredged and Non-Dredged Basins

open access: yesLimnological Review
The objective of this study was to assess the growth rates and general body condition of two common game fishes (largemouth bass Micropterus nigricans and bluegill Lepomis macrochirus) in a productive midwestern USA lake, Lake Winona, 20+ years after one

Post‐Release Survival of the Pelagic Stingray (Pteroplatytrygon violacea, Bonaparte, 1832) in French Longline Fisheries in the Northwestern Mediterranean Sea

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Bycatch remains a critical challenge in global fisheries, even when using selective gears such as longlines. In the French longline fishery targeting Atlantic bluefin tuna (Thunnus thynnus) in the Gulf of Lion, the common pelagic stingray (Pteroplatytrygon violacea) is the primary bycatch species.

Catastrophic shifts in the aquatic primary production revealed by a small low-flow section of tropical downstream after dredging

open access: yesBrazilian Journal of Biology
Dredging is a catastrophic disturbance that directly affects key biological processes in aquatic ecosystems, especially in those small and shallow. In the tropics, metabolic responses could still be enhanced by the high temperatures and solar incidence ...
